Q.	By selling a TV set for ₹ 12000, a dealer makes a loss of $14 \frac{2}{7} %$ . At what price should he have sold it so as to get a profit of $7 \frac{1}{7} %$ ?

$14 \frac{2}{7} %$ = $\frac{1}{7}$ $7 \frac{1}{7} % = \frac{1}{14}$

Profit % and Loss % are given in fraction.

Hence, we take the CP = 1

Loss = $\frac{1}{7}$ SP = 1 - $\frac{1}{7}$ = $\frac{6}{7}$

Profit = $\frac{1}{14}$ SP = 1 + $\frac{1}{14}$ = $\frac{15}{14}$

As per the question, $\frac{6}{7}$ = 12000

$\frac{15}{14}$ = $12000 \times \frac{7}{6} \times \frac{15}{14} = ₹ 15000$
